Anti-theft Feature

WARNING: This page is about a different car, the 2009 Acura MDX, 2008 Acura MDX, and 2007 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

The navigation system and audio unit have a coded theft protection circuit. Make sure you have the anti-theft security code before:

After service, reconnect power to the navigation unit, and turn the ignition switch to ON (II). Enter the 4-digit anti-theft security code, then select Done.

If the code cannot be found, use the interactive Network (iN) to look it up. You can view the serial number in one of the Navi ECU diagnostic screen (see VERSION  ). Alternatively, you will need the serial number from the navigation unit under the driver's seat.

When replacing the navigation unit, be sure to give the client the new anti-theft security code.
